@JAKEISGREAT , @pdac1975-----Your right! Vegas was neutered at 4 months old. He is 2.5 years old now. His body and his head filled out perfectly. He weighs 63 and has for a year and a half. I don't think he has a "huge" head, lol, I think it fits his big broad chest nicely. We adopted Vegas when he was 4.5 months old so he was already neutered. I would have done it immediately if he wasent already. BUT like @savemejeebus--it did not curb his desire to "hump" at all!! He humps all the time still. We have worked so hard to correct this bad behavior, putting him down, etc..does not matter....My name is Kelly....and my dog Vegas is a HUMPER!!!!!
